Abstract
A supercharged internal combustion engine of the type having an exhaust gas turbine driven supercharging blower, exhaust gas bypass for regulating the exhaust gas turbine by diverting exhaust gases around the turbine, and a blow-off valve control charging air bypass for circulating charging air supplied from the blower therearound when an engine performance control member such as a throttle is closed, is improved by provision of a second charging air bypass for circulating a portion of the air supplied by the blower therearound in response to at least one operating parameter of the engine in a manner so as to provide protection against excess charging pressure. The at least one operating parameter for controlling the second bypass includes engine rpm and/or charge pressure and opening of the second bypass may be regulated by a solenoid valve controlled by a safety switch responsive to charging air pressure or an rpm transducer such as an ignition pulse transducer.
